Four years ago, Neil Mehta was among the 15 million people who watched Ken Jennings and Brad Rutter—the world’s greatest “Jeopardy!” players—lose to an IBM-designed collection of circuits and algorithms called Watson.

“Jeopardy!” is a television game show in which the host challenges contestants with answers for which they must then supply the questions—a task that involves some seriously complicated cognition. Artificial-intelligence experts described Watson’s triumph as even more extraordinary than IBM supercomputer Deep Blue’s history-making 1997 defeat of chess grandmaster Garry Kasparov.

Modern life now often depends on GPS(short for Global Positioning System), but it can err on the order of meters in cities. Now a new study from a team of Dutch researchers reveals a terrestrial positioning system based on existing telecommunications networks can deliver geolocation info accurate to within 10 centimeters in metropolitan areas.

The scientists detailed their findings 16 November in the journal Nature.

A 300-millimeter wafer from a GlobalFoundries fab in Dresden is full of advanced transistors. The industry will need to continue to produce more and better devices, argues the author.

This is a guest post in recognition of the 75th anniversary of the invention of the transistor. It is adapted from an essay in the July 2022 IEEE Electron Device Society Newsletter. The views expressed here are solely those of the author and do not represent positions of IEEE Spectrum or the IEEE.

On the 75th anniversary of the invention of the transistor, a device to which I have devoted my entire career, I’d like to answer two questions: Does the world need better transistors? And if so, what will they be like?

NYU Biomedical Engineering Speeds Research from Lab Bench to Bedside

Intensive clinical collaboration is fueling growth of NYU Tandon’s biomedical engineering program

This optical tomography device that can be used to recognize and track breast cancer, without the negative effects of previous imaging technology. It uses near-infrared light to shine into breast tissue and measure light attenuation that is caused by the propagation through the affected tissue.

This is a sponsored article brought to you by NYU’s Tandon School of Engineering.

When Andreas H. Hielscher, the chair of the biomedical engineering (BME) department at NYU’s Tandon School of Engineering, arrived at his new position, he saw raw potential. NYU Tandon had undergone a meteoric rise in its U.S. News & World Report graduate ranking in recent years, skyrocketing 47 spots since 2009. At the same time, the NYU Grossman School of Medicine had shot from the thirties to the #2 spot in the country for research. The two scientific powerhouses, sitting on opposite banks of the East River, offered Hielscher a unique opportunity: to work at the intersection of engineering and healthcare research, with the unmet clinical needs and clinician feedback from NYU’s world-renowned medical program directly informing new areas of development, exploration, and testing.
